Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Vibration bringing colour :P

this may not be a "maya basics" but i have no idea what to do user added image

i want to make a wine glass, completely transparent so you cant see it, then something taps it and the vibrations from the tap you can see shiver up it, and as they shiver up it i want the glassy look to appear. not just appear and fade in, but make the colours appear properly following the vibrations user added image any idea how? user added image

I believe that would be done through animation, no? Simple key framing should do it. I would also turn on motion blur in your render global settings as well.

*grabs a wine glass*....... *flicks the top section*........*observes*

Hmm. Well, appears as though the rim of the glass is the only part that really vibrates dispite the fact that the glass is one object.

Realiztically, I believe the only way you could achieve this effect is by animating the actual vertices near the top of the wine glass. I do not recommend doing this for two reasons:

1) We can achieve the same effect by animating the entire glass as opposed to animating the vertices, which will be a lot easier and faster. The only drawback to doing this is that your vibration will be seen on the base of your wine glass, which is unrealistic. This, however, is ok because......

2) you will not be seeing the base of the glass in the animation anyway. Am I telling you how to do your animation? Partialy, yes. I believe that the effect will only be noticable if your camera is right up next to the rim of the glass. Otherwise, you might as well not even fool with this effect unless you can *see* the effect, no?

Conclusion: animate the entire glass. This should be done very carefuly though because it is obviously very easy to "overanimate" the glass. You want to barely move it. I would key every frame as well, otherwise you will get a smooth transition from one position to another.

I would probably try to use an expression. Would set driven key work with this?

There are probably other ways to achieve this effect. This way is only one....

i was thinking more of a "matrix bullet ring" effect shivvering down it ring by ring and dissappearing, some form of particle effect i believe. but the problem would be making the glasses colour appear following the rings, like say, its like you have a glass tube and you cant see it, but as you fill it up you see it appear, that kind of effect but in reverse user added image

You could possibly map a black to white ramp to your transparancy and animate the ramp to achieve such an effect.

What about making the glass a soft body and setting one of those springy elastic field things around it?

I think mike's idea of a color ramp, animated, sounds like a good idea - why don't you try it?

I'll give it a shot and see what happens. I have been trying to work with glass myself... but being a newbie, things take a lot of time...

good luck
